Application filed larch 27, 1925. Serial No. 18,717,

This invention relates to hinges and particularly to hinges employing sheet metal hinge butts or what are commonly known as hinge butts and more particularly to what 6 are known ascovered joint hinges; and the object of the invention is to provide a hinge of the class specified, one of the butts of which is fashioned from a comparatively heavy sheet metal blank and fashioned to form at one end portion thereof a curved hood member substantially semi-circular in formin cross'section'and provided with an enlarged pintle bearing portion within said hood portion, said bearing portion being fashioned from the material of the blank,

I and said bearing portion forming on the opposite sides thereof and within the hood portion, recesses for receiving the pintle bearin of the other butt of the hinge; a

further object being to provide ahinge butt of the class specified, the pintle. bearing portion of which around the pintle aperture thereof isof greater dimensions than the thickness of the blank from which the butt is formed; a further object being to provide a hinge butt of the class specified which is so formed from a sheet metal blank as to provide a pintle bearing portion, the entirety of which is fashioned into a homogeneous mass which is also integral or one with the adjacent portion of the hinge butt: and with these and other objects in view, the invention consists in a hinge butt of the class and for the purpose specified, which is simple in construction, eflicient and strong and durable in use, and which is constructed as hereinafter ,described and claimed.

The invention is fully disclosed in the following specification, of'which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters 111 each of the views, and in which:

Fig. 3 is a side edge view of the blank parformatlon thereof as the des1red result may Fig. 5 is a side edge view of the structure shown in Fig. 4:.

In Fig. 1 of the drawing, I have shown at 10, one of the butts of a hinge known as a covered joint hinge, and at 11 I have shown the otherv buttof 'the' hinge. My present invention relates primarily to the formation of the butt 10 from a single piece of sheet metal, of such thickness as to give the required strength thereto. In Fig. 2 of the drawing,'I have shown a blank 12 from which the hinge butt 10 is formed, said blank being of the same thickness throughout its length and one end portion being cut away. to form at the opposite sides thereof, recesses 13 'and a central. projecting tongue member 14. The first step in forming the hinge consists in rolling the tongue member and the adjacent end portion of the hinge to form a substantially cylindrical body 15 of said tongue member 14- and the adjacent portion of the b'lankas seen in Fig. 3 of the drawing, after which the cylindrical body 15 is fashioned by suitable dies or other means to form a curved hood member 16 at the end portion of the hinge, the free edge of which forms a stop shoulder 17 and centrally within the curved hood portion, which is substantially semi-circular in form in cross section, is an enlarged pintle bearing 18. The above briefly described .operation of forming the hinge'butt is more clearly shown and described in a companion application filed by me of equal date herewith and also shown and described in my application No. 14,037, filed March 9, 1925, in which applications, the method only of forming the hinge butt is claimed.

In the foregoing operation of forming the pintle bearing 18 and hood portion 16, it is preferred that the hinge butt or that end portion thereof which is fashioned in the manner described, be heated by any suitable means so that in the finished formation of the pintle bearing 18, the entirety thereof will constitute a. homogeneous mass which. will be integral or united with the adjacent surrounding body of the butt proper. However, it will be understood that I am not necessarily limited to heating the butt in the 10! be accomplished by a series of successive forming operations and including annealing operations, if the same are required.

After the pintle bearing 18 has been formed in the manner set out, the aperture 19 is drilled therein to receive the pintle pin which also passes through the knuckles or pintle bearings of the hinge butt 11, which knuckles or bearings enter and operate in the recesses 20 at the opposite sides'of the bearing 18 and Within the hood portion 16.

With the present construction, it will be understood that the recesses 20 open outwardly through the opposite sides of the butt 10, and the pintle bearings of the butt 11 are exposed therethrough. the hood 16 functioning to cover the joint of the hinge around the face thereof only as will be apparent, and it will be understood that by reason of the fact that the entire hinge butt is made from a single piece of sheet metal,

the butt may be produced at a lower cost than the making of hinge butts from eastings,forgings andthe like. \Vith my pres-' ent construction, I also provide a very strong and durable pintle bearing member 18, it being noted that the walls surrounding the major portion of the aperture 19 are of greater thickness than the thickness of the metal sheet from which the butt is formed and the shoulder portion 21 of the member 18 which abuts the top face of the shank of the butt reinforces and strengthens said bearing member; and While I have shown and described certain details of construction for carrying my invention into effect, it will be understood that I am not necessarily limited to the specific structure herein shown and described, and various changes therein and modifications thereof may be made within the scope of the appended claims without departing from the spirit of' my invention or sacrificing its advantages.

It Will also be apparent that with my improved construction or method of forming a hinge butt, the same may be made from a sheet metal blank of the same dimensions throughout or of a strip of metal of a given Width throughout its length, thus avoiding waste in the material used or in blankingmaterial from sheets to form enlarged end portions as has heretofore been the custom..

Having fully described my invention,

what I claim as new and desire to secure' by Letters Patent, is

1. A hing'e butt of the class described comprising a sheet metal body portion, one end of which is fashioned to'form a substantially semi-circular hood portion, and an enlarged pintle hearing within said hood portion and integral therewith, the' hood portion of said butt at the opposite sides of said pintle bearing tapering outwardly and terminating at the end thereof in a compara-' I tively narrow stop shoulder, and said body.

being pintle with recesses opening outwardly through the opposite sides of. said hinge butt.

provided at the opposite sides of the earing and within said hood portion 2. A hinge butt-of the class described comprising a sheet metal body portion, one end of which is fashioned to form a substantially semi-circular hood portion, and an enlarged pintle bearing within said hood portionand integral therewith, the hood portion of said butt at the opposite sides of said pintle bearing tapering outwardly and terminating at the end thereof in a comparatively narrow stop shoulder. said body being provided at the opposite sides of the pintle bearing and within said hood portion with recesses opening outwardly through the opposite sides of said hinge butt, and said pintle bearing being substantially of cylindrical formation and provided with a projecting shoulder portion lying adjacent one side face of the butt and serving to reinforce said pintle bearing.

3. A hinge butt fashioned from a single sheet of metal to form at one end portion thereof, a curved hood member, a substantially cylindrical pintle bearing Within said hood member, and said butt being provided at the opposite sides of the pintle bearing and within the hood member with recesses opening outwardly through the side edges of said butt. 1

4. A hinge butt fashioned from a single sheet of metal to form at one end portion thereof, a curved hood member, a substantially cylindrical pintle bearing within said hood member, said butt being provided at the opposite sides of the pintle bearing and within the hood member with recesses opening outwardly through the side edges of said butt, and the-formation of said pintle bearing being such as to unite the same with the adjacent portion of the butt.

5. A hinge butt fashioned from a single sheet of metal to form atone end portion thereof. a curved hood member. a substantially cylindrical pintle bearing within said .hood member, said butt being provided at the opposite sides of the pintle bearing and Within the hood member with recesses opening outwardly through the side edges of said butt, the formation of said pintle bearmg being such as to unite the same with the adjacent portion of the butt, and said hood portion at the opposite sides of the pintle bearing tapering outwardly and terminating at the end thereof in a shoulder portion.

6. A hinge buttfashioned from a single sheet of metal to form at one end portion thereof, a curved hood member, a substantiallv cylindrical pintle bearing within said hood member, said butt being provided at the opposite sides of the pintle bearing and within the hood member with recesses opening outwardly through the side edges of bearing tapering outwardly and terminating at the end thereof'in a shoulder portionfiand the formation of said hood and pintle bearing being such as 'to provide about the major portion of the circumference of said bearing, a wall of greater thickness than the sheet from which the butt is formed.
